To all whom, it may concern:

Be it known that I, VVILLrs B. THoMPsoN,

. I a citizen of the United States, residing at Steward, in the countyof Lee and State of Illinois, have invented certain newand usefulImprovements in Vehicle-Springs; and I do hereby declare the followingto v be a full, clear, and exact description of the This inventionrelates are regulated.-

i'nvent-ion, such as will enable others skilled in the art to which itappertains to make and use the same, I

to springs for vehicles such as heavy wagon s;.and it consists inthenovel construction and combination of the spring guiding attachmentshereinafter fully described and claimed, whereby the vertical movementsof the ground wheels In the drawings, Figure 1 is aside view of portionsof a vehicle provided with spring guiding attachments according to thisinvention. Fig. Qis a lan. view of the guide arms and shaft. F 1g. 3 isa detail view of one of the eye-bolt connections.

The body 2 of the vehicle is provided with a rear axle 3 and two similarground wheels 4, and 5 are leaf springs arranged between the axle andthe body, one at each end portion of the axle. Alt'df these parts are ofany approved construction. y In order to limit the vertical movement ofone ground wheel with relation to the other ground wheel, two eye-bolts6 are arranged to slide vertically and loosely in two bearing brackets 7which project from the arranged around the eye-bolts above and below thebearings, so that the eye-bolts may slide vertically and'tilt' toalimited extent in their bearings. A'shaft '10 is journaled loosely inthe eye-bolts, and extends cross- Wise underthe vehicle body.

Arms 11 project from the ends of this shaft,and the shaft and arms arepreferably formed intions of the arms ll'have laterally project copiesof thlspatent may be obtained for five cents each, by addressing ingpins .14 which engage loosely with hearing blocks 15, which". are boltedto the axle 3 'and arranged n'ea'r the leaf springs.

In passing overroug'h ground the vertical movements .ofo'ne Wheel aretransmitted to v the other wheel through the guiding arms andshaft,.which are formed of resilient material such as steel, and thebody is pre vented from tipping to an undesirable 'extent. This oftenprevents accidents and upsets, as one leaf spring can only go down to alimited extent farther than the other.

This device can beapplied toall kinds of wagons, heavy trucks andautomobiles What I claim is:

1. The combinatio'mwith a vehicle -borly an axle provided With roadwheels, and springs supporting the body from the axle; of bracketssecured one on each sidev of the vehicle body, supports free to rock andto slide vertically in the said brackets, springs between thesaidsupports and brackets, and v a cross-shaft journaled in the saidsupportsparallel to the axle and having longitirdi 2. The combination,with a wagon body, anaxle'pr'ovided with road wheels, and

'nally projecting arms at its ends which=arepivotally connected with thesaid axle.

springs supporting thebody fr m t 2 5] of brackets secured to thevehicle body one. at each side thereof, eye-bolts engaging with thesaidbrackets, helical springs arranged around the eye-bolts abo-veuand belowthe" brackets and permitting the. eye-bolts to tilt and to slidevertically, a shaft journaled in the eye-bolts and extendingcrosswise-under. i

the vehicle body and having arms at-its ends which terminate inlaterally pro-jecting pins, and bearing blocksfor the star pins securedto the end port-ions of the axle.

In testimony whereof 'Ihav'a'fiiXed my signature in the presenceoft-w'o' -witnesses. VV'ILLIS B. THOMPSON. Witnesses:
